C ++ boost :: thread并自动锁定容器 [英] C++ boost::thread and automatically locking containers

问题描述

有没有一种方法可以在访问时自动锁定STL容器，而不必锁定和释放它？

Is there a way to automatically lock an STL container on access, without having to lock and release around it?

推荐答案

当前的C ++标准未提及STL容器的线程安全性。正式而言，STL实现可能是线程安全的，但这是非常不寻常的。如果您的STL实现不是线程安全的，那么您将需要锁定并释放它或寻找其他方式来协调访问。

The currrent C++ standard does not say anything about thread safety for STL containers. Officially it is possible for an STL implementation to be thread safe, but it's very unusual. If your STL implementation is not thread safe, then you will need to "lock and release around it" or find some other way to coordinate access.
